Study of the correlation between the effects of phenamine and reserpine on models of the caudate arrest reaction]

Chronic experiments were conducted on cats. It was revealed that the effect of d, 1-amphetamine reducing the inhibitory effects of the caudate nucleus on the motor function persisted after the reserpinization of the animals. Reduction of the inhibitory function of the caudate nucleus in the form of increased threshold of the causate retardation of movement under the effect of d,1-amphetamine was expressed more 24 hours after the administration of large doses of reserpine (0.3 mg'kg). This could be the result of increased sensitivity of dopaminergic receptors of the niqro-striate routes to the mediator by the principle of denervation.     

A new gene of a TrfA type replication initiator found in a caprolactam/salicylate degradation plasmid pBS270

A mini-replicon was obtained for the caprolactam/salicylate degradation plasmid pBS270 (105 kb) of incompatibility group P-7 from Pseudomonas bacteria, and its nucleotide sequence was determined. A new gene that encodes a TrfA-like replication initiator was found on this replicon. The level of homology between this replication initiator and known proteins of the TrfA family suggests that the obtained replicon can be classified as IncP-1-like. The pBS270mini was shown to be chimeric.     

Transcriptomic response to differentiation induction

Background  

Microarrays used for gene expression studies yield large amounts of data. The processing of such data typically leads to lists of differentially-regulated genes. A common terminal data analysis step is to map pathways of potentially interrelated genes.     

Identification of the Key Genes of Naphthalene Catabolism in Soil DNA

The key genesnahAc and xylEof the naphthalene catabolism of fluorescent Pseudomonas spp. in total soil DNA samples were detected by the polymerase chain reaction (PCR) technique. The collection of fluorescent Pseudomonas spp. was screened for the occurrence of these genes. The results obtained show the possibility of using this approach in the goal-directed search for plasmid-containing naphthalene-degrading fluorescent pseudomonads in soil. The distribution of the naphthalene catabolism genes in soils contaminated with creosote and petroleum products was also studied.
